I've investigated cyber threats and security incidents for Alyn Inc., NightWing, Raytheon Technologies, the U.S. Social Security Administration, and Boeing.

At Alyn Inc., I analyze packet captures, security logs, compromised hosts, suspicious email links, and malicious files to determine root causes and recommend remediation. I also optimize detections and tuning in Splunk and CrowdStrike while contributing clear incident communications and reporting.

At NightWing and Raytheon Technologies, I built and deployed Splunk alerts, enterprise detection signatures, CrowdStrike automated workflows, and threat-hunting activities informed by OSINT-derived IOCs, TTPs, and MITRE ATT&CK.

I've also served as a Lead Analyst and SME, developing SOPs and training while supporting customers, stakeholders, threat intelligence teams, and Blue/Red Team engagements.
